Running Benchmarks in Multiple Mode#
Intel(R) MPI Benchmarks provides a set of elementary MPI benchmarks.
You can run all benchmarks in the following modes:
Standard (or non-multiple, default) – the benchmarks run in a single process group.
Multiple – the benchmarks run in several process groups.
In the multiple mode, the number of groups may differ depending on the
benchmark. For example, if PingPong
is running on N≥4 processes, N/2
separate groups of two processes are formed. These process groups are
running PingPong
simultaneously. Thus, the benchmarks of the single
transfer class behave as parallel transfer benchmarks when run in the
multiple mode.
